Examining Java Performance With Standard Benchmarks

Zusammenfassung

Standard benchmarks (e.g. DaCapo, ScalaBench, SPECjvm, SPECjbb) are often used to examine performance of JVM tools or JVM modifications. Unfortunately, because both the benchmarks and the environment are complex, it is not very clear what conclusions can be reliably drawn from simple measurements. We provide some information comparing the expectations and reality, based on our experience from using standard benchmarks to track one year progress in the development of Graal, an aggressively optimizing JIT compiler for the JVM.
